Operation by Manual Override

WarningDisassembly and Reassembly

CautionOperation

Closed state (Vertical slot) Open state (Horizontal slot)

Opening the valve: Turn 90° clockwise by a flat head screwdriver to open the valve. Besides, the valve remains in the open state even when a screwdriver is detached.

Closing the valve: Turn 90° counterclockwise from the open state to the original state to close the valve.

Perform an eletrical operation at the position where the valve is closed.

• Cut off the electrical power and pressure supply, and release the residual pressure before dissembling.

• Disassembly procedure1. Remove the mounting

screws on the top.2. Remove the solenoid coil,

spring and armature assembly.

3. If foreign matter is adhering to the parts, perform an appropriate procedure, such as blowing with air or cleaning with neutral detergent.

• Assembly procedureRe-assemble by following the disassembly procedure in the reverse order.When changing the electrical entry direction, mount it in the direction that solenoid coils will be mounted.

Note 1) For series VCA30, the end of the spring with the smaller O.D. is fitted over the armature ass'y. Be sure to make this distinction when assembling.

Note 2) Tighten the four mounting screws in a diagonally crossing order, and use the proper tightening torque below.

Glossary

1. Maximum operating pressure differentialThis indicates the maximum pressure differential (inlet and outlet pressure differential) which can be allowed for operation with the valve closed or open.

2. Maximum operating pressureThis indicates the limit of pressure that can be applied inside the pipelines. (Line pressure)

3. Withstand pressureThe pressure which must be withstood without a drop in performance after returning to the operating pressure range (The value under the prescribed conditions).

Pressure

1. MaterialHNBR: Nitrile hydride rubber

2. JIS symbolIn the JIS symbol ( ) IN and OUT are in a blocked condition ( ), but actually in the case of reverse pressure (OUT > IN), there is a limit to the blocking capability.( ) is used to indicate that blocking of reverse pressure is not possible.

Others

1. Surge voltageA high voltage which is momentarily in the shut-off unit by shutting off the power.
